DESCRIPTIONForms the quotient of two frequency domain images. The first input is taken as the numerator and the second as the denominator. The numerator value is used for the quotient if the denominator at that point is zero. This operation is useful for image filtering and restoration operations. The inputs must be frequency domain images in the packed format produced by the ForwardFFTImg module (see format description in ForwardFFTImg documentation). The Fourier transformation and the cross correlation are discussed in:
